OK Its done Springs Installed with kyb struts, Car is 1978 280z with sbc with jtr mounts which I installed 15 years ago.
The suspension in the car was original springs with 15 year old gas struts with 15 inch zx rims and 205 60 tires
Stock sway bar in front no sway bar in back
After Installation of the Eibach springs the car sits 3/4 inch lower front and back (eibach says 1 to 1 1/4 )
Ride quality is much better, stiff but you still have movement.
For $189 for springs and $200 for shocks total its a deal.
Rear installation only required half shafts,e brake cable and brake line never touched the a arms
